A U.S. Marine sergeant who posted critical comments about President Obama on his Facebook page will be dismissed with an "other-than-honorable discharge," the Marine Corps said today.

Newt Gingrich has experienced a long slide since March 6, when he won Georgia's Republican primary. It was his second and final victory of the campaign season, but Gingrich fought to stay in the race through a Southern strategy that never caught on.

On Wednesday, a source close to the Gingrich campaign told NPR that he would officially suspend his campaign next week, and was likely to formally endorse Mitt Romney.

Teenagers can be pretty creative in their pursuit of a cheap buzz. Last month we reported on the "cinnamon challenge," which involves snarfing down a spoonful of the powdered spice.

Now we've got teens quaffing hand sanitizer, and ending up sick in the ER.

"My focus is getting justice for Trayvon, if it takes me the rest of my life. I am dedicated and committed to getting justice, so I can wait a year."

That's what Sybrina Fulton, the mother of Trayvon Martin, told Tell Me More's Michel Martin today, when Michel raised the potential that the trial against George Zimmerman could go on for a year.

After an admirable effort by the upstart Miami Cuban community, the people have chosen Tampa as the true home of the Cuban sandwich.

More than 7,200 people voted here at The Salt, and the results speak for themselves: 57 percent chose Tampa, 43 percent went for Miami as the first city of the Cuban sandwich.

The U.S. Postal Service is so much a part of this country, it's in the Constitution. And yet with so much written communication now delivered via email, text messages and the Internet, the Postal Service is steadily losing business and operating in the red.

Most people wouldn't think of Washington, D.C., as one of R&B's great cities. Despite the fact that soul music greats Marvin Gaye and Roberta Flack grew up in D.C. neighborhoods, the city never had the equivalent of Detroit's Berry Gordy and Motown, or Memphis' Willie Mitchell and Hi Records. But in the early 1970s, D.C. did have producer Robert Williams and his Red, Black and Green Productions. A new compilation album called Eccentric Soul: A Red Black Green Production revisits Williams' influence on the sound of R&B in D.C.

Allegations that Wal-Mart officials in Mexico paid local authorities to speed up permits to build new stores could result in a trial and a huge financial penalty under a U.S. anti-corruption law. But legal experts who spoke to NPR have their doubts it will ever come to that.

Making a living practicing medicine is more complicated and frustrating than ever. But it still pays. And pretty well.

A survey of more than 24,000 doctors conducted online for Medscape, a doctor-oriented information service of WebMD, finds that their average annual pay ranges from $156,000 for pediatricians, the lowest-paid specialty, to $315,000 for the top earners.

Federal Reserve Chairman Ben Bernanke said the Fed is ready to implement "balance sheet actions if necessary."

That means if the Federal Open Market Committee feels that the economic recovery is in danger, it is ready to implement a third round of quantitative easing, or bond purchases intended to bring down long-term interest rates and spur borrowing and spending.

"If appropriate... we remain entirely prepared to take additional action," the chairman said. "We will not hesitate to use them."

As I write this, it's about 1 a.m. in Nepal and, according to National Geographic magazine's iPad app, a group of climbers is camped on the side of Mount Everest, possibly sleeping (though we can't be totally sure), at nearly 21,000 feet. They expect to make a final summit push in early May.

President Obama's urbane coolness, viewed by many as an attractive feature of his personality, was part of the joke Tuesday night when he appeared on Late Night With Jimmy Fallon, including in the "slow jammin' the news" segment.

After years of cuts to public school budgets across the country, many districts are relying on parents to pay for classroom supplies, extracurricular activities and even teacher salaries. But some worry that uneven distribution of funds will widen disparities between schools and between districts.

At airports, train stations and other public places across the nation, the Department of Homeland Security's "See Something, Say Something" campaign has encouraged people to report suspicious activity in an effort to prevent terrorist attacks. But a recent government survey found citizens are not jumping in to report others.

Anders Breivik testified that he was sane during his shooting and bombing spree, but argues that he did not commit a crime. He hoped they would force Norway to change its policy on immigration. Peter Talos, a reporter for the Norwegian News Agency, talks about what this case has meant for Norway.

Mitt Romney swept all five primaries on Tuesday, solidifying his hold on the GOP presidential nomination. Newt Gingrich made a last stand in Delaware, but came up short and aides to the former House speaker say he plans to suspend his campaign soon and will likely endorse Romney.

SB 1070, the Arizona immigration law that requires local police to question and detain people suspected of being in the country illegally, has served as a model for similar legislation. Los Angeles Times and Chicago Tribune Supreme Court correspondent David Savage listened in on the arguments.
